Welcome to vim, but if you go overboard on plugins then you will have the same issues with it, probably more so.
I'm finding with Vim that less is more, or maybe as I become more experience I'm not relying so much on the GUI aspect of text editors (creating new files, git integration, color pickers, etc) but instead just sticking to the command line for a variety of operations.
After setting Vim up for multiple environments (PHP, Go, Python, and JavaScript) it's now my daily driver. Maybe other people feel similar?
